Reply To: is there any way to display the thumbnails of all categories on mobile.

Hi,

If you decide to switch from WoodMart Child to WoodMart, you may need to adjust some of your settings and configurations to match the new theme. We recommend installing a child theme as all the settings and customizations would remain the same after the theme update.

Please find here information on the child theme:
