Project Online > Project Detail Page > Custom field's drop-down choice doesn't auto select subchoice

Hi all,

I'm configuring a project detail page for an enterprise project type.

I've created a custom field which shows choices from a lookup table like this. You can see that the lookup table contains choices in 2 levels

I put this custom field in the PDP page to capture new project information

Our users expect that when we check the box of a level-1 choice, all the choices in level 2 should be auto selected. But it doesn't work that way, user still has to manually select each choice in level 2 which can be time consuming. We are planning to create a similar custom field which contain like 10+ choices so we want it to be easy.

Please kindly advise how can I solve this?

Thank you very much in advance.

Regards,

Nichanal
