Hello everyone!

I have found a somewhat reliable method to resize the columns in tree:

Create an scss file whith your choice of name (like custom_tree.scss) and inside it write the following:

.custom__tree {
    [data-name="product_id"] {
        width: 800px; //or what value you want, it can be in % as well    
    }
}
 
//next add the scss file to the assets like:
< template id="assets_backend" name="custom table assets" inherit_id="web.assets_backend">
    < xpath expr=" / / script[last()]" position="after">
        < link rel="stylesheet" type="text/scss" href=" / module_name / static / src / scss / custom_tree.scss" / >
    < / xpath>
< / template>

    
        
    


// in your view just add to the < tree >  element the class "custom__tree"
// note that it works even if it is added by xpath

Hi,

Please try to inherit base fields which all you want and put inline css with !important. By default odoo will take the core css and using !important we can override the particular style.

if you want to reduce size of Quantity

<field name="qty" style="width:20px !important;"/>

Hope this will help you.

Thanks

You can do this via custom CSS. create a file css and give there your own columns width.

Like that:

<template id="assets_login_backend" inherit_id="web.assets_backend">
    <xpath expr="." position="inside">
        <link rel="stylesheet" href="/yourmodulename/static/src/css/web_backend_style.css"/>
    </xpath>

</template> 

then do css according to your need. I have done this once. If you will feel any issue let me know. I will help you in that.

Thank
