My question is how do i get the grails navigation plugin to show subItems?
I did a simple thing and added the following to top of my Controller:
class DummyController {
static navigation = [group: 'tabs',
title: 'dummy',
action: 'list',
subItems: ['create', 'save']
def create = {....
In main.gsp I added the following:
<head>
...
<nav:resources/>
</head>
<div id="menu">
<nav:render group="tabs"/><br/>
<nav:renderSubItems group="tabs"/>
</div>
Expecting this to work instead i get an exception:
Cannot invoke method toLowerCase() on null object
Jira has this bug filed and someone mentions adding:
if(!controllerName) return out
To the top of def renderSubItems function in NavigationTagLib.groovy which i have. It now no longer throws that error but my sub-menu items still dont display.
Any help on how to get the sub-menus displaying would be greatly appreicated
Thanks
It seems it did work, when a menu item is selected the new page loads and shows 'create' and 'save' underneath on the new page.
I misunderstood and was expecting the subitems to appear before i clicked on the menu button, or if i hovered over the menu button. I wanted to use the YUI css and let nav plugin do the hardwork but this is not the style of menu im after. I wanted a more dynamic menu i.e. you hover over a menu item and it shows a dropdown of subitems allowing you to go directly to an action much like the YUI menubar.

I am creating a MVC application in which on the Left Side Menu will load first time when the user Login into the application and on click of any of the Menu Option only Right side Content will display(Will Call the Action Method).
I have achieved it using Partial Views. Is it good to create whole application on Partial Views or is there any other way to achieve this?
Looks like you want to load the page for which the link is clicked, in an asynchronous way. You can do that using jQuery ajax methods.
So first, mark your links with a css class name so we can use that as the jQuery selector to wire up the ajaxfied load behavior. You should also has a content page to which we will load the result of the ajax call.
<div>
<div id="leftPane">
About
Contact
Index
<div>
<div id="rightPane">
</div>
</div>
Now you can listen to the click event on those link, use jQuery load method to get the content of those action method and update the rightPane's innerHtml
$(function(){
$("a.alink").click(function(e){
e.preventDefault();
$("#rightPane").load($(this).attr("href"));
});
});
With proper css, you can keep the leftPane to the left side of the container and rightPane to the right side of that.
I am having an issue with Bootstrap Modal, you know when we call a modal, the page where we called it is disabled (it turns gray) and you can only type/click on the modal right? On my part though, both the main page and the modal is disabled so I can't click nor close my modal after I called it. I can fix it by making the data-backdrop property to false but that removes the effect both on my modal and the page.
Default Modal:
data-backdrop = "false"
I think the reason for this is because the content of my modal is a partial view, and the modal is called from a partial view also. To help you imagine: I have 3 pages
1. Index.cshtml(main page)
2. SearchResult.cshtml (partial view)
3. Edit.cshtl (partial view)
Index is where my search criteria bar, when Go is clicked, SearchResult partial view is called at the center of the page, then when I click edit, the modal popup.
My assumption is that the backdrop also disables my SearchResult so my whole page become disabled. I am not really sure though. I hope you can help me figure this out. Thank you!
Do you have an example of your code? I am guessing without looking that your div that you are populating with the modal content is inside the div(s) with the rest of your page content. If this is the case, try moving the modal div out of any nested tags so that it stands on its own.
I.E.
`<div id="PageContent"></div>
<div id="ModalContent"></div>`
I put this code on my document ready , to catch when that element is adding to the page and I remove his css attribute position to relative:
$('body').on('DOMNodeInserted', '.modal-backdrop', function () {
$(this).css('position','relative');
});
Working on making a very standard dropdown menu with the new jquery ui 1.9 menu widget, but having some problems due to the newness of the widget and the presence of only a single extremely basic example at jqueryui.com
Specifically, can anyone here help me to:
Initialize a widget with no icons for submenus? (Default is a right-facing carat and I can't get rid of it)
Make a menu where user has to click on the top menu item (as opposed to just hovering) to make the submenu appear? Any deeper submenus should then expand when the user's pointer hovers over them. This is typical dropdown behavior, e.g., user clicks "edit" to make options appear like "select" or "undo", but any further choices under (for example) "select" would apper just by hovering over "select". I hope that's clear.
Thanks
I don't know how to do the second part of your question but I can answer the first question.
You can change the default icon by setting the icon option of the menu option.
First add a class to your CSS file like this.
.no-icon { display:none;}
Then set the icon option when you create the menu.
$( "#menu" ).menu(
{ icons: { submenu: "no-icon" } }
);
You won't have any icons.
Here is a fiddle
So I have a listview with multiple items, so when each item is clicked it will go to a detail page, but how do I fill out the detail view with dynamic contents? Specifically, how do I capture the key, which is the clicked item's inner html, and when I query some dynamic contents, how do I put them in the detail view? The methods I tried include 1) use click event for each item, but the event does not trigger, is that normal? 2) I tried the live event on the detail view page with pagebeforeshow, but it does not trigger either. Please help.
Many approaches exist to do this. Here is one idea that may help you:
In your listview, specify a data ID for each of the hyperlinks in the list item. The definitions could look like:
<li><a data-id="some-identifier">My Title</a></li>
For all the items the <li> items in the list, you then have a single click handler, which would use the data-id to initialize the detail page. The click handler would look something like this (my apologies if this is out of data, I have not recently used jQuery Mobile, so there may be an updated, better approach):
$('#my-listview-id').delegate('a', 'vclick', function () {
alert ('user selected something: ' + $(this).attr('data-id'));
});
The alert will show you the ID the user selected. So in the click handler you can update the detail page.
I've seen in Joomla documentation the way to detect if you are in Frontpage while creating a template in Joomla 2.5. This is the code:
<?php
$app = JFactory::getApplication();
$menu = $app->getMenu();
if ($menu->getActive() == $menu->getDefault()) {
echo 'This is the front page';
}
?>
This works when you are at home page (or clicking on Home menu), but I have an slider in home page, and I link in the slider to an article which is not in any menu item in the application. When I load this article the code above returns as I were at frontpage. I guess that if I doesn't click on any menu item, $menu->getActive() doesn't change.
Any suggestion?
Thanks in advance.
You can do one thing to solve this problem. Create a hidden menu of all the article links which are linked in the sliders.By creating hidden menu the link will be initialized and $menu->getActive() will work for all the links..Hopefully it will works for you .
I wish to add to the present answer and provide some clarifications.
In order for the menu selection to be detected the page requires to be assigned to a menu item. If this is a hidden menu than the link to such a page called My Page would be:
/index.php/my-page - “my-page” is the menu title alias for this item
However, if one wants to show the correct hierarchy in the breadcrumbs for the same page, then the menu hierarchy would have to be replicated in the hidden menu.
For example if My Page is under My Articles main menu item, then in the hidden menu you should add “My Articles” item, of the type: Menu Item Alias, which is in the Systems submenu of the menu type field. The My Page item should be a sub-menu item of My Articles.
The “My Articles” menu item in the hidden menu must have a different menu alias than the same one in the main menu hence the new link to My Page would look like:
/index.php/my-articles2/my-page
To create a hidden menu, one simply creates another menu. It does not matter whether one creates a module for it or not, but if one does then one just should not assign any position to that module.
