[gd_cpt_categories] layout

Try adding this CSS:

.gd-cptcat-ul.gd-cptcat-parent.gd-cpt-flat {
    display: inherit;
}

Thanks

You can add this CSS to make sure the categories in the popular category widget do not line-break:

.geodir-cat-list ul li {min-width: 220px;}

They are ordered by “popularity”, categories with most listings come first.

Not sure how you are adding the CPT widget to the homepage, but review https://wpgeodirectory.com/docs/core-shortcodes/#ctp-cats
You could add this CSS:

.gd-cptcat-row .gd-cptcat-li {
    max-height: 150px;
    overflow: hidden;
}

Also review https://wpgeodirectory.com/docs/customizing-your-style/
Small CSS tweaks are not that hard, and are not part of support.

I have no idea where you are adding the CSS but if I add it to GD > Design > Scripts > CSS, it works for me.

That would require quite a bit more customization which is outside support. Thanks
