I currently using ahDoctrineEasyEmbeddedRelationsPlugin to embed a Block form into a Page form.
All works well, but I'd like to hide the label of the embeddedRelation.
I've created a 'homepage-main-top' Block within the Page form in the admin, now when editting this Page, I now see 'homepage-main-top' is randomly appearing before the embedded block relation
Looking at the plugin docs, there doesn't seem to be anything relating to removing/hiding this:

Does anyone know how to not display this?
Thanks
I've been struggeling with somewhat the same problem, only I needed to style the label instead of hidding / stripping it.
From what I've found out there is no simple way to manipulate the label of the embedded form, but I figured the following 'hack'.
The embedRelation method accepts a inner- and outer-decorator parameter. You can use these to wrap extra markup around the label and the embedded form. You can then use CSS to hide the label using a specific id / css class.
By openning tags in the outerdecorator and closing them in the inner decorator you can wrap the label in a tag (which is rendered inbetween the two). It is kind of tricky to make sure your HTML is still valid.
I know this is kind of a crappy solution but I haven't found a better way up until now.
Add this line to your parent form:
$this->widgetSchema['EmbeddedFormName']->setLabel(' ');
If the above doesn't work, try using the 'newFormLabel' option (from the plugin's documentation).
$this->embedRelations(array(
'RelationName' => array(
// ...
'newFormLabel' => ' ',
// ...
),
// ...
));

From this question (Hyperlink inside label field in Vaadin 12) I was able to use Vaadin's HTML component to create custom html code (and it worked fine, including putting in ahref links etc.)
However, Vaadin provides the "Anchor" component which appears to be the far more powerful (and potentially more secure) way of creating links that can be used to navigate to either other classes I built or to external website (or even to download dynamically generated data in a streaming fashion).
However, what if I want to have both normal "label-like" text and an achor link all appear in a single paragraph? For example, in "normal html", I could just do this:
<p>
This is my normal text.
Download <a href="/resources/excelTemplate.xlsx" download> this Excel file</a>
and follow the instructions therein
</p>
and it would create the link somewhere within my <p>...</p> paragraph. How can I do this in Vaadin with the Anchor object? The best I came up with thus far is to use Horizontal Layout and then add a label, an achor, and then another label -- but that is really really ugly and doesn't technically have the same effect (it won't wrap properly.) The other option is to NOT use "Anchor" but instead just use "HTML" component and just create ahref links everywhere, but that seems a tiny big ugly too (though I suppose it's an ok workaround.). (I'm assuming I can call any UI I build by sticking the url links in the ahref calls....) Thoughts on the "right Java Vaadin" way to do this?
Paragraph p = new Paragraph("para");
Anchor a = new Anchor("go", "www.go.com");
p.add(a);
p.addClickListener(e-> UI.getCurrent().navigate(a.getHref()));
Vaadin 10+ offers you (atleast) three ways to handle this kind of case. You mentioned two of the..
Make composition of components in Java. Instead of VerticalLayout you could wrap the content in Div and using Text component also in Div instead of Label. You can make this kind of custom component by extending Composite.
The second alternative is to use HTML component as you mentioned.
The third alternative is to create custom html polymer template and connect to it with PolymerTemplate class. That will result in custom component that behaves like the custom component of the first option. It is just different way of implementation.
Which one of the three is a correct way. From framework perspective all of them. Which one is correct for you depends on your preference and application.
With a grails app and from a local database, I'm returning some text in a xml format.
I can return it well formed in a <textarea></textarea> tag with the correct indenting (tabulation, line return,...etc.)
I want to go a bit further. In the text I'm returning, there are some <img/> tags and I'd like to replace those tag by the real images themselves.
I searched around and found no solution as of now. I understood that you can't add an image to a textarea (other then in a background), and if I choose a div tag, I won't have the indenting anymore (and therefore, harder to read)
I was wondering if using a <g:textField/> or an other tag from the grails library will do the trick. And if so, How can I append them to a page using jquery.
For example, how to append a <g:textField/> in jquery. It doesn't interpret it and I get this error
SyntaxError: missing ) after argument list [Break On This Error]...+doc).append("<input type="text" id="FTMAP_"+nb_sec+"" ...
And in my javascript file, I have
$("#FTM_"+doc).append("<g:textField id='FTMAP_"+nb_sec+"' ... />
Any possible solutions ?
EDIT
I did forget to mention that my final intentions are to be able to modify the text (tags included) and to have a nice and neat indentation so that it is the easiest possible for the end user.
You are asking a few different questions:
1. Can I use a single HTML tag to include images inside pre-formatted text.
No. You will have to parse the text and translate it into styled text yourself.
2. Is there a tag in the grails standard tags to accomplish this for me?
No.
3. How can I add grails tags from my javascript code.
Grails tags are processed on the server-side, and javascript is processed on the client. This means you cannot directly add grails tags via javascript.
There are a couple methods that can accomplish the same result, however:
You can set a javascript variable to the rendered content of a grails tag. This solution is good for data that is known at the time of the initial request.
var tagOutput = "${g.textField(/* etc */)}";
You can make an ajax request for the content to be added. Then your server-side grails code can render the tags you need. This is better for realtime data, or data that will be updated more than once on a single rendered page.
I'm trying to set a set of fields to be dynamically displayed on demand. In the model, I've the fields:
attr_accessible ... :instruct1, :instruct2, ... :instruct30
I would like the form to display just instruct1 with a button to add 1 more field until instruct30 is hit and a button to remove one until instruct 1 is hit. All should happen without refreshing page which i think would include some use of AJAX but I couldn't find anything that is similar.
I've searched for something similar but only able to come up with nested form which is not what im looking for as my model is fixed.
The majority of your work is going to be on the client side.
To add and remove form fields dynamically, you have to use javascript.
Check out the HTML that Rails generates for the first field, replicate that and add the additional fields using for example jQuery.
A crude example:
$("#button").click(function() {
$("#theForm")
.append('<input id="instruct2" name="object[instruct2]" type="text">');
});
You'd have to keep track of how many fields you've added or removed.
For the Jquery UI tag-it widget, I'd like to disable text input into the class="ui-widget-content ui-autocomplete-input" textbox which contains all the tags.
My purpose is to just allow certain people the ability to delete inappropriate tags, but not allow anybody to add tags (which are auto-generated).
Is the best thing for me to edit the tag-it .js file and add a disable="disable" for that field? If I do that, won't that prevent the contents of that field from being submitted? Or does that matter as long as the associated hidden field is submitted?
Or is there a better way of doing this (an overriding style?) without modifying the tag-it file itself?
Thanks,

In tag-it.js I replaced this line:
this._tagInput = $('<input type="text"').addClass('ui-widget-content');
with this:
this._tagInput = $('<input type="text" readonly="readonly"/>').addClass('ui-widget-content');
adding the readonly="readonly" attribute. That had the desired effect of preventing input but still allowing users to delete inappropriate auto-generated tags.
I had the same question as original op.
But as the question is 2 and a half years old, and tag-it version is changed.
The accepted answer needs to be updated to the folowing in
tag-it.js around line 478:
from:
if (this.options.readOnly){
tag.addClass('tagit-choice-read-only');
}
To:
if (this.options.readOnly){
tag.addClass('tagit-choice-editable');
// Button for removing the tag.
var removeTagIcon = $('<span></span>')
.addClass('ui-icon ui-icon-close');
var removeTag = $('<a><span class="text-icon">\xd7</span></a>') // \xd7 is an X
.addClass('tagit-close')
.append(removeTagIcon)
.click(function(e) {
// Removes a tag when the little 'x' is clicked.
that.removeTag(tag);
});
tag.append(removeTag);
}
This is under the documentation of git repository having the documentation, under the Properties section:
$("#myTags").data("ui-tagit").tagInput.addClass("fancy"); //Obviously
if you want to do something with class...
This translates to the solution for this below, in my personal implementation style, and probably the only way I could get this to work:
$("#myTags").data("ui-tagit").tagInput.prop('disabled' , true);
This is if I understand your question correctly.
Note: ReadOnly does not make the tags un-editable.
As far as going through the tags, you could use ..
var x = $("#myTags").tagit("assignedTags");
Make it as an input field, and that ensures its "singleFieldNode" meaning tags are , (comma) separated. That way you can parse through it (split for commas(,) into an object, or however you want to do it)
PS: To apply any of the snippets above, simply change to the "id" of the HTML element that contains TagIt, and your code would work correctly.

is there any way (or plugin) to display editable combobox? I have a set of options, but I would like to give possibility to enter custom value.
I've searched the documentation, and I can't find way to do this. I made workaround with javascript, but I'm looking for more elegant solution.
I'm pretty sure that there simply is no HTML form element that does this, and so Rails can't provide you with a helper. As you said, you can work with JS to create something similar (and there should be JS libraries/plugins already out there), or you could just use a select element and add a text field next to it for new values.
HTML5 specification doesn't define such an element. So you may either continue using JS, either try to use autocomplete feature of an input element (although it is not exactly what you want and doesn't compatible with old browsers).
