table contain select all checkbox and the second for the single checkbox and some text

the code for the first checkbox for select all checkbox and the second for the single checkbox

Answer 1

In your component you want to have an array to hold the selected checkboxes in:

public array $selectedItems = [];

Then, in your blade you want to link your checkbox to this array:

<input type="checkbox" value="{{ $item->id }}" wire:model="selectedItems">

Now you can count($selectedItems) in your blade, or count($this->selectedItems) in your component to know how many are selected.

Answer 2

Try something like this

<input
id="my-id"
wire:model="yourCheckboxModel"
type="checkbox"
@if($yourLivewireVariable)
checked
@endif>

You can use a blade if endif statement to toggle the checked variable, and then use wire model to bound the variable
