Seems that this control has a limit of 25 items?? seems really low considering the old one had a limit of 500. Hoping this is just for the time being and on realease they will have at least 500 back.
Mollet,
Yes, it is definitely just for the time being. This control will certainly be improved before it comes out of preview.
this dropdown can’t show more than 25 items, you can check this
Ahemd,
Good call out on the limitations. I suspect this is going to be improved soon.
Control doesn’t support searching either, so seems like much improvement is needed before it can be used in production apps.
Also can’t display more than 1 field! Geeze, kinda sucks.
Sim,
Early release. Give it time.
Is it possible to use these modern dropdown controls for cascading? I’ve not had any luck getting this to work.
Yes you can do cascading. Here is code for a dropdown that changes the 2nd one.
First Dropdown is called drpFeatureType and 2nd is called drpFeatureSubType.
For the first one, add this code:
Sort(ForAll(Distinct(YOURDATABASE, Title), {Result: ThisRecord.Value}), Result, SortOrder.Ascending)
and make sure you select the Title in the Edit field of the dropdown.
Then add
Sort(Filter(DFERequestTypes,Title=drpFeatureType.Selected.Result), SubType, SortOrder.Ascending)
to the 2nd dropdown and make sure to add SubType to the Edit Fields area.
Hi Matthew,
thanks for the post, very intersting.
I am playing with these new visuals, especially this dropdown, I like the look 🙂
It seems I cannot assign a value from a gallery item like ThisItem.SomeField into the DefaultSelectedItems.
This looks surprising to me. Does it mean we can’t bind default values from a datasource? Wih the old dropdown we can do this.
With new Input Text we can. With new Checkbox we can’t…
Or am I missing something?
Thanks!
My list is blank (Choices([@’My list’].Column)) – but controlling selection with a textbox and code DropdownCanvas1.Selected.Title I can see that the values are there. Is it font color = to background color?? Drives me crazy.
Preben,
No themeing yet. It’s coming.
I have problems with defining the DefaultSelectedItems property.
Items – [“08″,”09″,”10″,”11″,”12″,”13″,”14″,”15″,”16″,”17″,”18”]
How would I define a default value in this simple scenario? Thanks in advance!
Edit: The only solution I found is to define Items as Table({},{},{} … and then set the specific table record as default. It’s a pain to configure.
Currently unable to specify a table of SearchFields like in the old combobox. Restricted to searching on a single field even though multiple can added.
Am I being dense, or is there no way to set the ‘Items’ property to use a Distinct function? I’ve attempted to port my “old” dropdowns to the new, modern ones, and every time I nest my field in a Distinct() function, the list comes back as blank.
Hello,
Any success with setting DefaultSelectedItems property? It’s not working consistently in my app, I have property set to the below. This is within a gallery.
Filter(
colScores1,
Response = ThisItem.Response
)
Thank you,
{Value: “YourValueHere”}
I cannot seem to find a way to clear the selection of a modern dropdown. The legacy one had a setting to allow that. How do we clear the selection on the modern control?
I agree. It should have the “allow empty selection” like in the old control. Seems a fundamental need. Surprised it came out of “preview” without it. @Matthew – have you heard whether they get on this?
Hi Matthew,
there isn’t a Reset property for this control. I have about 10-15 controls in my app that I’d like to reset using boolean variable on the Reset property. I could do it with classic controls but how do I do that with modern controls?
Mohammed,
Do it by changing the DefaultSelectedItems property
hi Matt
have you come across the problem like me and others with the modern drop down not showing the data?

Luke,
No, but I don’t use it yet. It’s still in preview and not ready for apps 🙂
Hello,
I was experiencing the same issue with the data not showing. However, if I don’t select a data source when first inserting the dropdown, the data show up.
I like the look. However, it does not update immediately I select a new value.
When a new value is selected, the dropdown choices will disappear which is good. However, it will go back to showing the old value for about two seconds before the one you selected shows up.
I am forced to do a loading icon, so users expect a delay after selecting a new value. It is unnecessary though since the choices are mere integers, not large records.
