Odoo Space Between Buttons on Top Tree View

Question

I'm able to create a button when select multiple record by adding this header tag in tree view

<tree create="false" delete="false">
    <header>
        <button name="action_cancel" type="object" string="Cancel" class="btn-danger"/>
    </header>
    ...
    ...
</tree>

As you can see, there is no space button 8 selected button and cancel button. How can I add a space for that buttons?

Answer 1

You can add ml4 class to action_cancel button

<button name="action_cancel" type="object" string="Cancel" class="btn-danger ml4"/>

Or alter the o_list_selection_box and define the right margin:

.o_list_selection_box {
    margin-right: 4px;
}

Alter the web.assets_backend template to add the CSS file
