Checkbox on/off, how to change value value?

Question

css

The site has a form in which there is a select and the user must select one of the options.
But it's not usable and I want to change it to "switch" (input checkbox) on/off.

The checkbox is in the same bootstrap component: https://getbootstrap.com/docs/4.3/components/forms...

Depending on whether the checkbox is enabled or disabled, you need to change the value value to open or closed.

<select name="status">

<option value="open"></option>
<option value="closed"></option>

</select>

на 

<input type="checkbox" class="custom-control-input" name="status" value="">

Tell me, good people, how?
