I was looking for creating inputs to select the machine size as Small, Medium and large where it should have a values of CPU & Memory and count of VMs to provision the machines through catalog
Sorry, I’m not sure what the question is. Are you just looking for general information on how to accomplish this?
If so you are going to want to make a form. You will have at least one input with the type ‘Plan’ for sizing (or if you only want some plans to show in the list you can make a custom option list with a translation script), and another option for the number of VMs.
You would then add the form to the catalog item and add the custom options in the config.
Vars look like this <%=customOptions.input_field_name<%>
As always, in Morpheus, there are a lot of different ways to accomplish the same thing but this route will probably be your best bet.
You can find more detailed info in our docs
