I have a form which works as a filter and consist of select, text field and few buttons (1-10). Select and the text field works, they reload the page, repopulate them self (keep the value chosen by user) and sent the data to the controller.

{{Form::select('nameOfSelect', ['item1' => 'value1', 'item2' => 'value2',], null, ['class'=> 'css-style', 'onchange' => 'this.form.submit()'])}}

{{Form::text('search', '', ['class'=> 'css-style', 'placeholder' => 'Search'])}}

With var_dump($request->all()); I can display the values of the elements.

How would a button look like which gives back a value? What I need:
<button class="CSS" name="5" value="5" type="submit">5</button>

The docs* provide this for a submit button:

{{Form::submit('Click Me!')}} //don't give back a value
{{Form::submit('Click Me!', 'XXXvalue)}} //error

//I tried this and get an error
{{Form::submit('Click Me!', '', 'xxx',['class'=> 'btn btn-outline-success mr-2','onchange' => 'this.form.submit()'])}}
//error message Illegal string offset 'name', 
//Note: '', must be avaible in Form::text, therefore I added it to Form::submit, don't work with or without it.

Thank you.
