I’m just to dumb to get the solution. Please help me. I have several pages with subpages: ``` PAGE A SUBPAGE A1 SUBPAGE A2 SUBPAGE A3 PAGE B SUBPAGE B1 SUBPAGE B2 SUBPAGE B3 PAGE C SUBPAGE C1 SUBPAGE C2 SUBPAGE C3 ``` Now I have a slider and I want to link the slider elements based on two fields: PAGE and SUBPAGE. So in my blueprint I will integrate two select fields and for the first one (to select PAGE A, B or C) I’m using it like this: ``` anchor_rubrik: label: Anker Rubrik type: select default: '' options: query query: page: / fetch: visibleChildren value: '{{slug}}' text: '{{title}}' ``` Then I want my options in the second field based on the value of the first field. So when I chose PAGE B for the field “anchor\_rubrik” I want the options [SUBPAGE B1, SUBPAGE B2, SUBPAGE B3] for my field “anchor\_single”. How can I achieve this? Thanks in advance for the help! ---

You need a custom field with some JS that listens on the first field and then fetches and injects the options into the second field. ---

Is there any example out there for inspiration? 😉 ---

Maybe you can find something [here](https://github.com/jenstornell/kirby-plugins/issues), I can’t recall a particular plugin at the moment… ---

is there a way to do it without JS, maybe after saving the document you will get all the options? ---

That should be possible, if your field queries a field on the same page, but probably isn’t very intuitive if the user has to save the page before being able to select another field option. See [https://getkirby.com/docs/cheatsheet/panel-fields/select](https://getkirby.com/docs/cheatsheet/panel-fields/select), option from other field. ---

I’m doing it now like this. Then I can see in the list what is the URL tree of the file. It works and that’s okay for me now. Thanks anyway for your help!!! ``` link: label: Link type: select default: '' options: query query: page: / fetch: visibleGrandchildren value: '{{slug}}' text: '{{uri}}' ``` ---

Yep, that is a lot less overhead, as long as the list doesn’t get too long. ---
