How to reference between tables and key, and show the value of a textual column, not a key

[AvenaFernando]

I used the tutorial: FlooringEstimates.xlsx - https://powerapps.microsoft.com/en-us/tutorials/add-form/

But in the column: Category, I wanted a KEY to be written there, coming from another table (UNIQUE_ID_CATEGORY).

Is there a way to show the name: Carpet / Hardwood / Tile, from the ID_Category table, in the EditForm and ViewForm, but using the data from the FlooringEstimates table?

But when Edit or New record, to be able to choose in the Dropdown the names of the categories (Carpet / Hardwood), but being recorded in the table the key of each category (201F206C / 32E2FB58).

It is possible to record the category key, but selecting and showing the category name.

Update

I noticed that it used below the dropdown a form, and therefore it did not work, placing a gallery of text, has shown all the products of the category.

The Dropdown and Gallery accepts to receive data type table.

Form only one record.

But being careful to the table of a certain category does not have more than 500 items.
