Dropdown here would be such a great feature. ---

That doesn't look like the native dropdown. What are you using? ---

It is a native 8.3 dropdown of Object prop with Value members. What I would like to achieve, to have a prop called interface, which would be a dropdown with only one option to choose. Probably not achievable, because I haven't found any info about it, but doesn't hurt to ask 🙂 ---

My first thought is that perhaps you could achieve this functionality by using a single parameter that accepts an input integer. Then, you can pass a number between 0 - N, where N is the number of choices you planned to provide within your drop-down menu. For example, define a (value-type) parameter called "interface" that will receive a number between 0-3, where each integer represents one of your four "options": `0 received >> "circuitMK3" selected` `1 received >> "circuitMK4" selected` `2 received >> "master" selected` `3 received >> "slave" selected` Anything else \>\> Invalid Entry (Fallback) Then, if you want/need to correspond these four "states" to four individual boolean variables, simply define your four booleans under the view's "Custom Properties" (_not_ "Params"), and then add a property binding to each one. So for your first choice/boolean, "circuitMK3",that would look like: `Custom Properties >> "circuitMK3" >> Configure Binding...` `Property Binding >> Tie to "interface" parameter` `Add Transform >> Map Transform` `Input == 0 >> Output == true` `Fallback == false` Then, copy and paste this binding to your other three custom booleans, and modify the "input value" in the mappings such that each boolean corresponds to a different "interface" value (0-3 in this case). If you set it up this way, and make sure that each unique input value maps to only _one_ boolean variable (each boolean representing one of your "choices"), then you should achieve a structure that only allows 1 out of N choices (booleans) to be selected (true) at any given point in time. ---

This is a, semi-regularly, requested feature. Some examples below: > [@Perspective custom property type inferring](https://forum.inductiveautomation.com/t/perspective-custom-property-type-inferring/70654/2): > > At some point, we're planning to add the ability for you to define your own 'schema' for custom properties and view parameters; until then, your workaround is probably the best option. > [@\[IGN-1537\]Perspective Component param tooltips](https://forum.inductiveautomation.com/t/ign-1537-perspective-component-param-tooltips/53226/3): > > We have a feature in the backlog to allow defining your own schema for view parameters, such that you could do all the things we can do in props - define enums, define ‘suggestions’, define tooltips, etc. > [@Can you create a dropdown selection on embedded views?](https://forum.inductiveautomation.com/t/can-you-create-a-dropdown-selection-on-embedded-views/95728): > > I'm working on a reusable template that takes 2 integers as parameters. Currently they are magic numbers and only numbers 0-3 are meaningful to the template. I would like to add a parameter drop down to the template so that people can embed the view and click a drop down to select a valid option from a list when passing parameters in the designer. I don't think that's currently a feature but I figured I'd ask here because someone here will know if that's possible. It will be implemented at some stage in the future... fingers crossed! ---

Okay, thanks for your replies
