multiselect limit

Hello everyone.

I have a question I'm using Relation input and when I set max method but I can select more than set. I don't know what is the mistake

example:

Relation::make('movement[event_id]')
->fromModel(App\Models\Event::class, 'name')
->empty()
->multiple()
->max(2)
->title(__('Event'))

I think that I have the solution to fix to read method max on Relation and Select field:

1. create a function to do that

const controllerRelation = () => {
  var selects = document.querySelectorAll('select');
  selects.forEach((select) => {
    const instance = select.tomselect;
    
    if(select.getAttribute('data-maximum-selection-length'))
      instance.settings.maxItems = select.getAttribute('data-maximum-selection-length')
  })

};

this function read all select and set the maximum selection can you do

2. Set in your Relation or Select method multiple ->multiple()
3. If you are using Relation add method max to set the maximum, ex: ->max(3) to set maximum 3 selection
4. If you are using Select add method set and add the attribute data-maximum-selection-length after the number, ex: ->set('data-maximum-selection-length', '3')
