At times, you may need to refine the data you require by filtering it to view the most relevant information. The Filter tab allows you to do that.
You can go to the Filter feature button on the top right side of your stack just above the columns. Select to filter your data. As with our Sort data feature, Stackby lets you filter each of your columns with the data that is most relevant to you (so yes, you can filter the data of each column individually and look at the final data the way you want it to be).
So if you have a date column in your stack and want to filter the tasks that were done the week before, you can select and do that in Stackby. Just select the relevant column and parameter filters that you need from the drop down menu.
Here is how to filter your data:
Now, even you can add multiple filter but just selecting columns.
