How to add label to the right side of checkbox in odoo-12

Hi im trying to design my checkbox in odoo i want it to have a label to the right side of the checkbox just like this

Any Idea how can I Achieve this?

I've tried adding <span>Percentage</span> After my field but its always breaking the line

Suppose you have two checkbox fields chk1 and chk2, To make them appear like in the picture you will need to:

Add two labels one with Discount Mode string and another with an empty string.
Add a div after each label which will contain the field and its label.

<group>
    <label for="chk1" string="Discount Mode"/>
    <div class="o_row">
        <field name="chk1"/>
        <label for="chk1"/>
    </div>

    <label for='chk2' string=""/>
    <div class="o_row">
        <field name="chk2"/>
        <label for="chk2"/>
    </div>
</group>

You can refer to weight field in Product -> Inventory (tab) -> logistics (group).
