CSS tips and tricks

Add your css on template

Code:

<template id="my_module_frontend" name="my_module assets" inherit_id="website_sale.assets_frontend">
    <xpath expr="//link[@rel='stylesheet']" position="after">
        <link rel="stylesheet" href="/my_module/static/src/css/main.css"/>
    </xpath>
</template>

website_sale.assets_frontend is what you inherits.

Hide fields

Hide all children (that have attribute bill=‘1’) of oe_website_sale class owner (that have attribute bill_enabled=‘0’):

.oe_website_sale[bill_enabled='0'] [bill='1']{
    display:none;
}
