Dropdown props parameter

[grzegorz.kaczmarczy1]

Hi,

is there an option to create a dropdown props parameter? interface parameter uses booleans and for proper functionality, you can only choose one. Dropdown here would be such a great feature.

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

[grzegorz.kaczmarczy1]

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

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

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?

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
