'Left justifying' a row of conditional elements?

Hi all, 

Sorry if this isn't the place for the question.  I'm looking to find out if it's possible to left justify conditional items on a layer, and have the space collapse to the left when an item isn't included on a label? 

Is it a built-in ability I'm not seeing?  Is it a VB scriptable thing?  

Any pointers would be appreciated. 

Thanks

  Hello Troy,
  
  Thank you for reaching us via our Community Forums.
  
  Unfortunately, in BarTender Designer it is not possible to directly left justify conditional items on a layer and have the space collapse to the left when an item is not included on a label. However, you can achieve a similar effect by using conditional formatting and scripting.

  Here's a general approach you can follow:

  1. Place all the conditional items on the layer, aligned to the left.
     
     
  2. Set the visibility of each item based on the conditions using conditional formatting. This means that when an item is not included on a label, it will be hidden.
     
     
  3. To collapse the space to the left when an item is hidden, you'll need to use scripting. BarTender supports VBScript, and you can utilize it to manipulate the positions of the objects dynamically.
     
     

  Here's an example script that demonstrates how you can achieve the collapsing effect:
  
  

  Sub OnPostPrompt

      Dim leftPosition As Integer
      Dim gapSize As Integer
      Dim i As Integer

      ' Set the initial left position and gap size
      leftPosition = 100 ' adjust as needed
      gapSize = 10 ' adjust as needed

      ' Loop through the conditional objects on the layer
      For i = 1 To Format.Objects.Count
          ' Check if the object is visible
          If Format.Objects.Item(i).Visible = True Then
              ' Set the position of the visible object
              Format.Objects.Item(i).Left = leftPosition
              ' Update the left position for the next object
              leftPosition = leftPosition + Format.Objects.Item(i).Width + gapSize
          End If
      Next

  End Sub

  
  In this script, you need to adjust the initial leftPosition and gapSize values according to your specific layout requirements. The script iterates through each object on the layer and checks if it's visible. If an object is visible, its left position is set to leftPosition, and leftPosition is updated to include the object's width and the desired gap size.

  By utilizing conditional formatting and the provided script, you should be able to achieve the effect of left justifying conditional items and collapsing the space to the left when an item is not included on the label. However, please remember you will have to modify the script and layout settings to fit your specific needs.
  
  I hope this helps!

  Not sure if something simpler could work here, rather than VB, just use multiple substrings and so the if the first string is empty the 2nd string would automatically move across to the left, as per the image below:
