Making Summarize optional in Alteryx app

[Paulomi]

Hi, 

I'm making an app where the following happens - 

1. The user feeds in an input file through a file browse
2. The user is asked a question - Do you want to summarize the data?
3. If they do not want to summarize the data, they simply click on the radio button and the data is not summarized. 
4. If they want to summarize the data, they can choose 0 to 3 fields and Alteryx summarizes the data based on those fields. 
5. Then the rest of the operations are performed on the dataset.

My issue is with point 4. How can I make the number of summarize fields optional? The user might want to summarize with one field, or two or three. I was able to implement all three fields, but stuck with summarizing with one or two.

Any ideas? 

Thanks in advance!

Hi @Paulomi just a suggestion but when a use clicks summarize cannot you not summarize all the fields in the app and then have a select tool immediately after deselecting those and when the end user selects the fields they want this is in turn updates the select tools ticks the relevant fields?

Hi @JosephSerpis I have some 200 fields. Will this approach not make the process too lengthy and increase run time?

Hi @Paulomi possibly my thought process was that it be easier to work with a select tool and just select the fields you wanted rather try and introduce user interactivity with the summarize tool.
