Hi, I am new to powerapps and currently, I need to do enhancements for these apps. I have a dropdown list for the month. I need to make sure the user only can choose the current and onwards month only. The previous month will be visible but the user cannot click it. So far I didn't find any way to do that requirement. Btw the month is from my master list in sharepoint. Here is my screenshot for my apps


Kindly need someone to assist me 🙂
Thank you in advance.
