Sort dynamic dropdown

[MANISH]

Hi Alex - Is it possible to sort the values alphabetically in a dynamic dropdown? 

Thanks

Manish

Hi Manish,

You can use the `xxf:sort()` function for this (see link below for more on
that function). For instance to sort the list of countries in reverse
alphabetical order, you would do:

xxf:sort(/countries/country, name, 'text', 'descending')

And replace `descending` by `ascending` to get the normal alphabetical
order. (I'm just doing the reverse here, as the service I've used already
returns a list sorted in alphabetical order, so you wouldn't see the
difference.) In the Form Builder Control Settings dialog you'd have
something like: dynamic-dropdown-xxf-sort.png

You'll let me know if this works for you!
