You can make it 'thinner' by right clicking, selecting properties, going to the layout tab and reducing the 'scrollbar width' option.
If you make a selection, on the far right of that selection around the edge of your box it should offer you a different cursor (the black column resizing cursor) - rather than just resize the box, first resize the "selection" column or the "field" column, and then you should be able to reduce the box size without encountering the horizontal scrollbar.
Thank you for feedback. It is interesting to use of text box with:
=' Current Selections: ' &
if(vShowCS = 1, ' Click Here To Hide',
if(isnull(GetCurrentSelections()), 'Nothing selected',
GetCurrentSelections(' | ', ': ', ',')))
However, it lacks ability to remove the selection. But I will add it as an indicator on the top of the screen,
Continuing the above context, if we look at the screen shot of Atsushi Saijo, I'm facing an issue with Fields column where FieldOne and FieldTwo are not column-width optimized so they'll be seen as FieldO and FieldT
Please let me know how to correct this issue. It's a standard Current selection box, not a custom one.
Thanks and regards,
If you hover your mouse over the end where the field name is truncated you will see the cursor change to indicate it can be used to resize the column. Left click and drag to give yourself more room here.
Giving more room to the column names though will in turn give you less room for the selection values.
What I tend to do is keep the current selection box minimised, with a counter of current selections. Users can then double click to maximise. An example of this can be seen here:
Alternatively you can use the app that morganaaron has posted a link to above which has a more dynamic selections box.
Hope that helps,
