Hello @mukeshmvs280496, Thanks for sharing the details with us. Now let me share the flow of the Attribute tab to you.
In the attribute section, vendors have two options: adding custom attributes or using predefined attributes. When vendors add custom attributes, they can specify their own attribute values. However, if they choose a preset attribute, they can select from the predefined options but there is no such option for them of adding custom values for those attributes.
Regarding the template file overriding, we have already added a fix for this issue on our GitHub. Please download the updated MultiVendorX plugin from here: https://github.com/user-promi/MultiVendorX.git.
After updating, you can modify the attribute tab by adding custom CSS or custom code to the template file. Ensure that your custom code follows the old structure of the tab.
Let us know if you have any further questions.
