Angular UI Bootstrap Typeahead - Apply a class when the element is added to the document body

In my current project, I am utilizing angular bootstrap typeahead with multiple instances. Some of these instances are directly appended to the body using the "typeahead-append-to-body" option. Now, I have a specific instance where I need to customize the presentation by adding a unique CSS class only to that particular instance's ul dropdown-menu. However, I am facing difficulties in achieving this customization as the typeahead is appended to the body, making it challenging to target specific elements.

For more information on angular bootstrap typeahead, you can visit http://angular-ui.github.io/bootstrap/#/typeahead

<input type="text" typeahead-append-to-body="true" typeahead="state as state.name for state in statesWithFlags | filter:{name:$viewValue}" typeahead-template-url="customTemplate.html">

I am looking for a solution where I can customize the presentation of a specific instance without affecting other instances. Directly targeting using "body > .dropdown-menu" will impact all instances, which is not the desired outcome.

Answer №1

It dawned on me that by utilizing css attribute selectors, I could target the specific html template being used.

By incorporating the attribute "typeahead-template-url = 'mysearchdropdownpage.html' " within the input typeahead element, I was able to implement the following in my stylesheet.

HTML

<input type="search" typeahead="searchItem for searchItem in searchTypeAhead" typeahead-template-url = 'mysearchdropdownpage.html' />

CSS

ul.dropdown-menu[template-url='mysearchdropdownpage.html']

This method proved to be effective and produced the desired results.

Answer №2

Essentially, you have the option to assign a specific class to the input tag in order to accurately target the dropdown menu...

<input class="u-targetting-typeahead" ...>

...then, within the stylesheet...

.u-targetting-typeahead > .dropdown-menu

...this will specifically target only that input's dropdown menu.

The dropdown menu is dynamically generated, while the input element is present in the HTML and serves as the anchor point for targeting specifics.

MODIFICATION

Considering...

typeahead-append-to-body (Defaults: false): Should the typeahead popup be appended to $body instead of the parent element?

If you opt for setting this to false, the aforementioned approach would be effective. It seems like the most sensible choice available.
