Hello,

I'm trying to use a HTML fied to display a specific tab.

In this tab I want to print a checkbox (not modifiable):

<div class="o_field_boolean o_field_widget custom-control custom-checkbox">
    <input type="checkbox" id="checkbox-{id_line}" disabled="">
</div>

But in the result, I have my tab with all my others values but for the checkbox nothing is displayed. When I inspect the element there is only the div with nothing inside:

<div class="o_field_boolean o_field_widget custom-control custom-checkbox">

</div>

How can I display a checkbox in a HTML field ?
