How to manage choices in glide_list type field

SunilKumar_P · ‎05-09-2025

Hi,

I have created a field of type 'glide_list' as users want to select multiple values in it and have added choices to this field. However, I am unable to add or remove options on this field based on other field value.

Any suggestions would be greatly appreciated.

Regards,

Sunil

Hey Sunil,

I did some testing on my own and I was able to get this to work (in contrast to my previous reply). This is a little experimental (and guesswork), so your millage may very. Try this in your onChange client script:

g_form.removeOption('choice.incident.<variable_name>', '<choice_value>');

Replace <variable_name> with the Column Name of your variable, and <choice_value> with your choice Value. If you are on a different table, try replacing incident with your table name (or inspect the HTML to see what is listed for that element).

Basically I inspected the HTML element for the Glide List field and saw that choice.incident was a prefix of the field name. Running g_form.RemoveOption() in my browser console successfully removed the option. See attached for examples.

Remember that you will need to use g_form.addOption() to re-add any options you removed client-side if needed.

Hope this helps! Let me know if you need an example of a client script.

@SunilKumar_P

Since that glide list is referring to sys_choice, those are sysIds, so you will have to add reference qualifier to filter

add or remove option won't work there.

Hi @Ankur Bawiskar - Thanks for your response. There is no reference as you can see below.

However, as this field type usually deals with sys_ids, let me try and get back to you.

@SunilKumar_P

did you try what value you get when you use alert?

I haven't used glide list with choice

Hi @Ankur Bawiskar , tried with sys_id and other possibilities as well but no luck. I'm not sure if there is a way to handle choices in glide_list.
