I have the following for a polymer web application. The whole page scrolls. I would like for the contents of and to scroll independently. foo has a longer view and bar is generally able to fit in the page with maybe a little vertical scrolling.
How do I make the two contents of vaadin-split-layout scroll independently vertically?
<app-drawer-layout fullbleed force-narrow>
<app-drawer slot="drawer">
<app-toolbar>
<div main-title>Models</div>
</app-toolbar>
<section>
<div style="margin-bottom:90px;width:100%;"></div>
</section>
</app-drawer>
<app-header-layout>
<app-header slot="header" fixed effects="waterfall">
<app-toolbar>
<paper-icon-button icon="menu" drawer-toggle></paper-icon-button>
<iron-icon id="logo" src="icon.svg"></iron-icon>
<div main-title>Spliter Sample</div>
</app-toolbar>
</app-header>
<section>
<vaadin-split-layout orientation="horizontal">
<foo></foo>
<bar></bar>
</vaadin-split-layout>
</section>
</app-header-layout>
</app-drawer-layout>
Thank you for any advice.
You can style the panels of a vaadin-split-layout as any other div as the panels are in the light DOM as you can see when inspecting their examples.
Thus give them an explicit height and an overflow:auto or overflow-y:auto; to enable scrolling. The style rules be placed in your usual CSS.
I'd like to place an icon inside a list-divider, but it seems that jQuery Mobile lets me apply data-icons to normal list items only and not to list items with data-role='list-divider' assigned.
Simply enough, I want the list-divider to display an info button for providing the user with more information about this category, which should look like so:
The point is, I'd like to place the info icon (with data-icon='info' or class='ui-icon-info') within the list-divider, while maintaining consistency in the overall style, i.e.:
The category is headed by a list-divider, and not by a list-item that is just styled to look like the list divider.
The icon is displayed on the right side, like the arrows in the list items below. The icon has to have the same style of appearance like the arrows, which means that it should not look like a button or have an extra frame around it.
The list-divider, or at least the icon, should be clickable, so the user is able to get the information about this category.
I'd preferably like to achieve this without any CSS customizations or JavaScript fiddling, using data-attributes only.
This is what I got (using jQuery Mobile 1.3.2):
List-item with data-icon:
<li data-theme='a' data-icon='info'><a href='#' onclick='alert("Some info...");'>Category: A</a></li>
Result:
Correct appearance of info-icon
Wrong appearance of category, because a normal list-item is used instead of a list-divider
Using a list-item with data-role='list-divider' assigned:
<li data-role='list-divider' data-icon='info'><a href='#' onclick='alert("Some info...");'>Category: A</a></li>
Result:
No icon at all
Wrong title appearance and only text is hyperlinked instead of the whole list-item
List-divider with info-button inside:
<li data-role='list-divider'>Category: A<a href='#' data-role='button' data-icon='info' data-mini='true' data-iconpos='notext' data-inline='true' data-theme='a' onclick='alert("Some info...");'>Category: A</a></li>
Result:
Info button has wrong appearance
The button has a border which I like to remove for consistency, so the icon is shown in its usual disc appearance. Removing data-role='button' doesn't help, because the button wouldn't be rendered at all and would therefore not show the icon.
The icon's position is not on the right side. I know it would be possible using data-iconpos='right', but I used this attribute for the icon-only (notext) layout already.
Category appearance is not pleasing, as the button increased its height. Even data-mini='true' didn't help.
I know there are a dozen of easy ways doing it the normal, less jQuery Mobile fixated way, but after 3 approaches, I'm eager to find out how this could be done with jQM.
This works, including the click, i just test it
<li data-role="list-divider">Test<div onclick='alert("Some info...");' class="ui-icon ui-icon-info" style="color:white;float:right"><div></li>
if the icon doesnt align with the rest of the icons add the below to the style
margin-right: -5px;
and change the pixels size to match the other icons
I'm working on a page with four (4) separate DIV elements that all are scrolled independently of each other. Using the answer here: `-webkit-overflow-scrolling: touch` broken for initially offscreen elements in iOS7 I was able to get most of the pages working. There are still a few pages where the DIV holding the main content cannot be scrolled vertically when a side DIV is expanded.
The page structure looks like this:
...
<div id="paneTop">...</div>
<div id="paneLeft" class="expanded">...</div>
<div id="paneCenter">
<div>
<div style="overflow: hidden;">
<div id="mainContent" style="overflow: auto;">...</div>
</div>
</div>
</div>
<div id="paneRight" class="expanded">...</div>
...
Setting the touchstart event listener on #paneCenter worked for most of the pages but those didn't have the extra layer of divs. I have tried setting the touchstart event listener on #mainContent and all the way up the chain but #mainContent will not scroll when #paneLeft is expanded even though it works when #paneLeft is collapsed and it works whether paneRight is expanded or not.
Note: this issue has only been identified on an iPad running iOS7.
This is the correct behavior. If you want it to scroll vertically but hide it horizontally, then target it specifically: overflow-x: hidden (to hide horizontal excess), and don't set anything to overflow-y. This allows for some good control over elements.
Im using horizontal radio buttons in jQuery mobile:
http://jquerymobile.com/test/docs/forms/radiobuttons/
When you make the fieldset horizontal the style changes and the round 'selected' bit goes away. Can this behavioral be disabled so it users the normal jQuery mobile styling?
Yes, but not in a easy way. This much I can remember. I don't have an example with myself, also don't want to rewrite it again.
First, what you need is a firebug plugin (or something similar) for Firefox or Chrome.
I. Horizontal radiobuttons have a disabled span used for round selection img. Enable it by giving it a display: block-inline (in that case give other div the same property, this will allow them to be in line, in other case they will overlap) or give both of them display: block; a float them to the left (don forget position: relative) .
I am talking about this:
<span class="ui-btn-text">List</span>
<span class="ui-icon ui-icon-radio-off ui-icon-shadow"> </span>
Top one is a text span and bottom one is an icon holder. Bottom one is disabled (display: none;) in case of horizontal group.
II. Second thing, on click/select prevent background color change. This will leave you with horizontal version of vertical radiobutton control group.
Hope this helps.
I was seeing a strange phenomena when using Scriptaculous BlindDown and SlideDown effects, where they would smoothly slide, and then at the very end, they would jump an additional amount, maybe 10% of the slide distance.
I already saw the note on the BlindDown page that you have to be sure not to use padding, which I'd already done.
I was still thinking that this must be my mistake somehow, when I noticed that I see the exact same thing happening on their demo page for Toggle when clicking on either the Blind or Slide demos:
http://wiki.github.com/madrobby/scriptaculous/effect-toggle
Firefox 3.6.7, Chrome 6, and Internet Explorer 8 all display this effect on my computer.
So I was thinking about just writing it off and either living with it or cutting the effect out, when I noticed that the page for BlindDown does not display this effect:
http://wiki.github.com/madrobby/scriptaculous/effect-blinddown
So there must be a way to make this work. On my page, the jump is occurring whether I directly use BlindDown/Slide or whether I use Toggle.
Has anyone out there used these and managed to do so without this problem? Any ideas on what the secret is?
It's usually due to margin or padding.
The element you're blind-downing mustn't have any margin or padding, or should have margin:0.1% so that contained margins don't collapse through the bounds of the element either. If you do this it'll be smooth as silk.
also - ensure you've set overflow:hidden
Enjoy.
(the other place it'll fall down is if you don't define height. If you do this little incantation before you animate it'll get and set you height without bothering anything else.
elem.setStyle({position:'absolute',visiblity:'invisible'});
elem.setStyle({'height':elem.getDimensions().height+'px'});
elem.setStyle({position:'relative',visibility:'visible'}); //or position:'static'
In my experience, the jumping is just a performance issue, which is effected by the system specs, browser, and complexity of the html content you are toggling. Some browsers like safari and chrome have a pretty good javascript engine making them more efficient.
I see this is happening for you even when using chrome though? Is the html content particularly complex, or your computer overloaded with applications running?
There is definitely a little very well known secret... Have you tried wrapping your content in an extra div container? You should consider this best practice and almost a requirement specifically when using Scriptaculous effects.
For example... Say you want to slideDown or Toggle a login form - and you have::
<div id="login-panel">
<input type="text" name="username" />
<button type="submit" name="send">Login</button>
</div>
All you have to do is add an extra inner div tag::
<div id="login-panel">
<div><!-- extra div here -->
<input type="text" name="username" />
<button type="submit" name="send">Login</button>
</div><!-- close it here -->
</div>
Now when you do something like Effect.toggle("login-panel", 'slide'); the transition should be much smoother and less jumpy. It may seem a little sloppy but it almost always helps. Hope this helps you!!
Keep in mind that when Scriptaculous begins an animation, the container that is being modified will be absolutely positioned and then a record of the height will be taken, similar to what danielsherson mentions. If however the container does not exist within a relatively positioned parent container, then the dimensions of the animating container may change quite drastically. The easiest way to test this is to modify your container using firebug to set the position to absolute. What happens? Did the height change? For the best results, there should be no change in the dimensions of your animating container when switching to absolute positioning. What happens to the rest of your document, such as content moving underneath, will not matter.
The padding/margin issue is a tricky one too since there really isn't a way to prevent the margins from overlapping and creating issues. Best way I found to address this is to set your animating container to float and then use the clearfix hack on a parent container to make sure nothing overlaps.
<body style="margin: 0 auto; width: 300px; position: relative; background: black;">
<div class="parent nonanimating clearfix">
<div class="animating" style="float: left; width: 100%; background: white;">
<div class="apply-your-margins-and-padding-here">
...content...
</div>
</div>
</div>
<div class="parent nonanimating clearfix">
<div class="animating" style="float: left; width: 100%; background: white;">
<div class="apply-your-margins-and-padding-here">
...content...
</div>
</div>
</div>
</body>
Note that the classes are not functional and just for reference to my comments with the exception of clearfix, which is the float clear hack. The backgrounds and widths are only specified to give a better example of what is happening. Add whatever animation you'd like to $$('.animating')
I use this one (there are many), all though it is old and I don't even design for many of the browsers this hack supports..
.clearfix:after {
content: ".";
display: block;
clear: both;
visibility: hidden;
height: 0;
}
.clearfix {
display: inline-block;
}
/* Hides from IE-mac \*/
* html .clearfix {height: 1%;}
.clearfix {display: block;}
/* End hide from IE-mac */
I don't think it's a performance issue at all. I'm having the same issue. The ONLY way I've been able to make it not jump is to define a height for the div I'm sliding. I realize that this is NOT a good solution but it's the only one I've been able to find. I've also tried adding the additional div and it had no effect on how the Effect.toggle slide worked.
If anyone else has any more info on this, I'm all ears.
To prevent a Scriptaculous effect from jumping or jerking, remove the 'style' attribute from the element which you are applying the Effect to.
This:
<div id="mydiv" style="padding:10px;margin:10px;">
<button onClick="new Effect.BlindUp('mydiv');" />
</div>
Becomes:
<div id="mydiv">
<button onClick="new Effect.BlindUp('mydiv');" />
</div>
The styling can be placed in a enclosed div like this:
<div id="mydiv">
<div style="padding:10px;margin:10px;">
<button onClick="new Effect.BlindUp('mydiv');" />
</div>
</div>
The problem is caused by Scriptaculous reapplying the element's (mydiv) inline style declarations after the effect has been performed.
I have found success with using position: relative; on the block element using the slide/blind animation. Make sure padding/margins are placed on the child elements and not the slide block element.
