Tell us what you are trying to do?
I'm trying to add bootstrap toggle in search field.
If this is not possible, can you suggest a compatible plugin to customize the search bar style?
Sorry, could you elaborate on what you mean by adding a Bootstrap toggle?
When you refer to the "search bar", do you mean the filter section added to a View block? With the block editor you have quite a few styling controls available to customise the appearance, but you are aiming for something particular that you cannot do with the normal styling controls?
Perhaps you have some screenshots of what you are aiming for.
yes exactly, by search bar I mean the filter section added to a View block.
I would like something more in terms of style than what the basic toolset offers, I thought about the bootstrap toogle js library (hidden link) but I don't understand if it is possible to apply it to the toolset elements.
A plugin that would allow me more customization would also be perfect.
There isn't really such an option without customising this yourself.
The legacy Views editor was designed to leverage Bootstrap, and if you go to Toolset > Settings you'll see options to add Bootstrap to the site. But that just goes up to Bootstrap version 4, which is now somewhat out of date, and it is unlikely work will be done on adding support for later versions now that the focus is on the block-editor, which doesn't depend on Bootstrap.
Referring to your particular example, that was for a Bootstrap extension, and so it would require manual customisation to enqueue its assets as required and initialise via JavaScript.
The challenge when trying to incorporate something like this with Views filter controls is that there is a limited ability to modify the markup of the controls output by the View (and libraries such as this Bootstrap extension typically depend on adding custom CSS classes or data-attributes to the inputs and possibly their containing markup elements). Within the editor when you select a search filter you can add custom CSS classes or an ID, but they might not target the required element (instead being added to the container, for example), and there is no provision for adding custom data attributes.
If your needs are limited to specific cases, such as portraying a checkbox as a toggle switch, for example, then I would say the best approach would be to find a tutorial for how to do that generically (codepen is usually full of examples of this kind of thing), and then try and adapt it to your View based on the actual markup for the filter controls output by the View on the front end.
If you try that and you get stuck, show me what you are attempting and I'll see if I can help.
