Filter Inputs

Remove all empty strings from a set of inputs.

Inputs

Input		Value
`input1`, `input2`, etc.	Required	Any number of input strings.

Outputs

Key	Value
`output1`, `output2`, etc.	Output strings matching all non-empty inputs. For instance, suppose the inputs are: `input1`="quick", `input2`="", `input3`="brown", `input4`="", `input5`="", `input6`="fox" Then the outputs will be: `output1`="quick", `output2`="brown", `output3`="fox" The non-empty strings are moved up and the empty strings are skipped.

Usage

This action is typically used to display a variable amount of information neatly. For instance, suppose you have a checklist of photos and comments, and you want to add it to a form table. But you know that the checklist doesn't always have information in each row — for example, the checklist may have data in rows 1, 6 and 8, with the remaining rows empty. When adding this to the form, you want to consolidate this into 3 consecutive rows rather than leaving empty rows, so that it looks neater. The Filter Inputs action allows you to do this.
