Hello @unkufem,
By default, it is not possible to add a bio tab on the store page. You can create an extra field on the vendor settings area and then print the value on the store page. You may need to add custom code to get an extra tab.
You can use this filter add_action( 'dokan_settings_form_bottom', array( $this, 'add_description_field' ), 10, 2 ); to add a new settings field on dokan-lite/templates/settings/store-form.php . Then write a function to save the field data. Then use this filter- add_filter( 'dokan_store_tabs', array( $this, 'add_description_tab' ), 10, 2 ); to create an extra tab on the store page and then write function to show the data.
Cheers!
