If your are rending tom-select component conditionally then you need to put the both the css and js in you livewire component.

Hope this helps!

Thank you so much. I beat my head against the wall trying to make mine work (it always broke when I selected an item).

I think I can reproduce the issue, though I don't understand why it is a problem:

See what happens if you put following just above <x-tom-select ... in your form blade:

<label for="testUser">WTF</label>

In my case, the addition of the label with id of tom select element snaps it when selecting an item!?!?! Am I seeing ghosts?

One other small change I made since my data id's are strings & @JSON throws double-quotes into the rendered blade, busting the alpine x-data attribute: In tom-select component, I changed

...
items: @json($selectedItems),
...

to

...
items: {{ json_encode($selectedItems) }},
...

It seems happy with that, though I've only tested with single string item.

BTW I just realized that adding a wire:key to that label tag addresses the problem. Very edge-y livewire dom diffing issue, I'd say. I would love if you could reproduce as it is lonely out here on the edge ...

@thumbtech use {{ collect($selectedItems) }} instead of {{ json_encode($selectedItems) }}. It works well for nested objects.

Just a lil late, by uhh 2 years. Had a ton of problems, with tom-select but this managed to send me in the correct direction thanks :)

I had written some code to allow for real-time updating of the item list and the selected value so that you can change those in php / server side and have it reflect in the selection.

The fork is here if anyone comes across this and need a more documented and implemented solution https://gist.github.com/CallumCarmicheal/3bcbfb178443c9a11c673be83530ac8d
