Filter dropdown months

[anonymia25]

Hello,
How do I filter a dropdown to only show current month and the next months?

Hi @anonymia25，

Based on the issue that you mentioned, do you want to display the current month and next month in a Dropdown?

Please set the Items property as below:

Table({Month:"CurrentMonth:"&Month(Today())},{Month:"NextMonth:"&Month(DateAdd(Today(), 1, Months))})

Thought this would be simple, but ended up creating a collection that you'd have to create OnStart and add to Item propery of the dropdown

Clear(colMonths);;
ClearCollect(
    NumberCollection;
    "1";
    "2";
    "3";
    "4";
    "5";
    "6";
    "7";
    "8";
    "9";
    "10";
    "11";
    "12"
);;
ForAll(
    FirstN(
        NumberCollection;
        12 - Value(
            Text(
                Today();
                "mm"
            )
        )
    );
    Collect(
        colMonths;
        {
            Number: Value(
                Text(
                    Today();
                    "mm"
                )
            ) + ThisRecord.Value;
            Month: Text(
                DateAdd(
                    Today();
                    Value(ThisRecord.Value);
                    Months
                );
                "mmm"
            )
        }
    )
)

In your App OnStart or Screen OnVisible, create a collection as:

Collect(AllMonths,Calendar.MonthsLong())

In your DropDown control, add Items as AllMonths and Default as Text(Today(),"mmmm")

Hi @v-qiaqi-msft,

Yes, I wanted to display the current month and the next months, for example this current month is July so the dropdown will list July until December..

How do I make the formula automatically calculate the current and the next months?
Thanks!

Hi, @happyume 

Your method is simple and easy to understand but I am wondering if the previous months can be hidden from the list? Meaning only show the current and future months? Thank you so much.

Hi @anonymia25,

I think you have something misunderstanding with my solution. It is dynamically based on the Today().

Just imagine that the current date is 1/5/2021, the Dropdown will always display 1 and 2. So as the following days.

The Today() function changes dynamically based on the time flies.

I think they want the dropdown to display todays month, and all the other months of this year between this month and the end of the year. The only solution I found is to create 2 collections on start, needed to determine the amount of months to be added to the collection, and to assign the appropiate month name.

Create a numbered collection like below

Collect(col_months,Calendar.MonthsLong());
ForAll(col_months,
Collect(colNumberedMonths,
Last(FirstN(AddColumns(col_months,
"RowNumber",
CountRows(colNumberedMonths)+1
),
CountRows(colNumberedMonths)+1
)
)
)
)

and then in Items property, Filter(colNumberedMonths,RowNumber>=Month(Today()))
