How to make a multi-select token with dynamic options that defaults to selecting all?

[augustallen4]

I have a dashboard which will dynamically return values in a separate multiselect token based on user input to an initial token. However, I would like the multiselect token to default to having all options selected with the ability to uncheck any option and remove them from results.

The functionality I am looking for is nearly identical to the "Fields to use for predicting" in the Machine Learning Toolkit but I cannot figure out how to see the source code in that app. The only difference is that I would like to default to having all values selected.

How about appending 'All' to your dynamic resultset, through the query and make it default value?

<Your search resultset>|append [|makeresults |eval columnname="All", columnvalue="*"]

then make this All as default value. you can do it from ui as well as from xml.

I'm looking to default to having all the values selected and then a user can remove any values they do not want. If there's a value for ALL then you have to deselect it and then click dozens of other values.

The functionality I'm looking for is more like a "select all" not just making "all" an option. If I could figure out how they did it in the machine learning toolkit that would be perfect.
