Select all / Control + A?

[Fossil01]

It seems that when inside a textfield Control + A is not working, is there any way to enable this?

I have a basic dropdown where users can select one option. I can only do backspace to clear the field but not select all and then backspace for example.

var config = {
    plugins: ['dropdown_input'],
    maxOptions: 100,
};

new TomSelect('#sidebarSearch', config);

<select id="sidebarSearch" name="t">
  <option selected value="-1">All Categories</option>
  <option selected value="bla">Blabla</option>
  <option selected value="bla">Blabla2</option>
</select>
