Hello Everyone,

I am wondering if it is possible to divide a dynamo code to run certain parts of the dynamo code. For example, if the user selects **Option A** then dynamo runs the nodes that belong to **Option A** a routine. If the user selects **Option B** , then dynamo runs the nodes that belong to **Option B** a routine.

… something like that.  
I appreciate any pointers.  
Thanks

I usually do this by blocking one stream and passing the other using logic gates, see below:

Sometimes I use this really basic definition, which works nicely in Dynamo Player with User Input. You can replace the “True/False” with Text, Number, Dropdown or anything that suits you.
