Hi @Kelvin Chan ,
If you will apply the sorting in the dimension list i.e. Cost Center list using the ‘Manage Items’ → Reorder feature, and then it will automatically show you the items in the reordered manner in the dropdown filter.
Dimension List : Before
Filter Dropdown : Before
Dimension List: After
Filter Dropdown: After updating the order of the items (in the Dimension list)
Detailed explanation for reordering
Hope this makes sense , let me know if it worked for you!
Hi,
As a simple example:
It’d be great to sort filtered "Planning Versions" by the "Item Variable" instead of the default dimension sort. I tested a custom sort in the "Set_Filter Planning Versions" metric, but it reverts to the dimension’s sort .

@Chahat is there an easier way to do this? I have a dimension list with 800+ items and I want it to show alphabetically in the dropdown.
Hi @ljanowski ,
At the moment it is not possible to do this in an easier way unfortunately. However, there is an idea submitted to have a default property for sorting. :
Hi @ljanowski in order to reorder your list faster, after clicking on “Manage Items”, you can directly click on the “Reorder” button in the list header.
This will let you select the property of your List you’d like to reorder by.

However, as mentioned, this will not enable a “dynamic reordering” meaning that each time new Items are being added to the List, you will have to reorder through that method again.
I hope this helps!
