Custom order filters using Admin UI Extension

Topic summary

A developer has built a custom Admin UI Extension that allows filtering Shopify orders by multiple tags simultaneously—a feature requested by their client and recommended by Shopify Support. The extension currently works as a standalone action modal where users can add tags to a list and fetch matching orders.

Integration Goals:
The developer wants to integrate this functionality deeper into Shopify’s existing orders UI through one of two approaches:

  1. Add the filtered tags to the existing filter interface so they appear alongside native filters
  2. If option 1 isn’t feasible, replace the orders displayed in the current UI with the custom-filtered results

Current Status:
The extension successfully fetches order data but lacks styling. The developer is seeking guidance on how to proceed with either integration approach and welcomes any assistance on implementation.

Hi, I need some help with building out my custom Admin UI extension.

A client I work for wants to be able to filter their orders on multiple tags at once. After some research and reaching out to Shopify Support as well, I was pointed in the direction of a custom Admin UI Extension ‘Admin Action’ to implement this. I’ve built out this Extension, and (while it’s not styled yet), it works perfectly in allowing a user to add tags to a list, and then using that list to fetch the correct orders that match the tags.

Now, I would love to integrate this app further into the existing orders UI through one of two ways:

  1. Have the new ‘filtered tags’ be added to the existing query that is used on the orders page, so that it just takes into account these multiple tags when filtering. Just like it would when filtering right now.
  2. If 1 is not possible, I am already fetching the orders data now. So we could also replace the orders that are shown in that UI now, with the data I fetched in that custom app.

Any help on working further on this is welcome.
Thanks in advance!!

Here is a screenshot of the current action modal. I fetch the data through that app once the user clicks ‘Filter’, and would love to then further execute what I mentioned above.

Sounds great! Feel free to reach out.
