I'm glad it's working.
I updated that library, customizing it, because the original version didn't work: so I adapted it to my bootstrap 5.3 project and now I can use bootstrap-select without problems. Regarding the ajaxselect class, I inserted it in case ajax-bootstrap-select is used because it uses bootstrap-select: in this case is useful to force the refresh of the list which, if very long, was not drawn correctly: at least in my case.
About backwards-compatible I think it's not a problem because if you need to use bootstrap-select in old version (bootstrap 3 or bootstrap 4) you can use old bootstrap-select; otherwise in bootstrap 5 you don't have an alternative because the current official version doesn't work (bootstra-select release v1.14.0-beta3) and this is the reason why I have updated/alterated that library in a new custom version for my project, but without the ambition of replacing the original project or library: it was something I did for myself and I published it thinking it could be useful for others too.
Thank you @abeverley
Thanks for this @mattymatty76 - works great for me. Can I just ask what the reason is for checking
hasClass('ajaxselect')? I found that it wasn't working for my ajax-select as I didn't have that class in my select element (I was initialising using JS). Once I added it in everything worked as expected, but this means it is not backwards-compatible and others may fall foul.
@abeverley if you have a form with some components including an ajax-bootstrap-select and a simple bootstrap-select, you can't discriminate between them if you don't put a class like ajaxselect at the component ajax-bootstrap-select: this because if you don't put a check and always apply this.setSize(true) to all selects, slows everything down tremendously especially if the simple bootstrap-selects are large: since simple bootstrap-select is loaded just one time when you open the form, you don't need to call setSize; whereas an ajax-bootstrap-select changes everytime you type a char, so you need to call setSize to force it to redraw correctly
@mattymatty76 I appreciate you. It is working for me.
Thanks to you it's a pleasure
Great Job, Thanks.
Thank you! It's a pleasure to hear that works and solves your problem
Hi,
@mattymatty76 , I tyr use this, but don´t work.
I'm use laravel and include by vite.
I don't know what's the problema.
Could you point me in the direction, perhaps?
Bootstrap 5.3; Laravel 10 wiht livewire 3.4.
Tks.
Hi @lindomar-pjs,
I'm very sorry but I'm not an expert in laravel: have you tried to find some guides like this:
https://wpdean.com/add-bootstrap-to-laravel
maybe it could be a solution, keep in mind that the library works in a context without frameworks, when you use it directly, but (I think) in your case you need to adapt it with the laravel ruls, but I repeat I'm not an expert and so I could say inaccuracies
can anyone point me to direction on how to use this with ajax source? using the same options i used on bootstrap-select.js shows error

Hey @mattymatty76, thanks for doing this!
Do you remember why you changed chunkSize from 40 to Number.MAX_VALUE on line 1009?
Hello :) in Ajax select there were some problems related to the resultset
and it's rendering... If I'm not wrong
