[AIMPED]

Hi @wagnerbrito welcome to the forums.

The dropdown value auto change base on first filter

Hi, I want to develop one page for monitoring process status. The csv file had processes and codes as below sample. [image] And I used pandas df[‘Process’] .unique() and df[‘CODE’].unique() for dropdown filter. How the code filter auto changed base on ‘Process’ value? For example, when I choose Process=B, the CODE only show CODE3&CODE4? [image]
