Gallery with multiple filters, show All Items

[DessiBroughton]

Ok, I'm having a mindblank and can't get past this formulaic hurdle 😞 

I have a gallery with 3x filter variables, which must work concurrently.

In each of the filters, I want there to be a "show/select all" option. I'd hoped to invoke the mighty * wildcard, but alas, no love in Power Apps. 

My current formula is not having the desired outcome. 

SortByColumns(Filter(SteelPulseR4,code = Code_Input.Text || Code_Input.Text = "<All>" && Quarter = Quarter_Input.Text || Quarter_Input.Text = "<All>" && Game = Dropdown1.SelectedText.Value),"start",Ascending)

SteelPulseR4 = datasource

code = gallery title

Code_Input = filter 1

Quarter = gallery subtitle

Quarter_Input = filter 2

Game = Gallery field 3

DropdownSelectedText.Value = filter 3

Help?

Hi @DessiBroughton ,]

You need to bracket and/or combinations - do you want this

SortByColumns(
   Filter(
      SteelPulseR4,
      (   
         code = Code_Input.Text || 
         Code_Input.Text = "<All>"
      ) && 
      (
         Quarter = Quarter_Input.Text || 
         Quarter_Input.Text = "<All>"
      ) && 
      Game = Dropdown1.SelectedText.Value
   ),
   "start",
   Ascending
)

or this

SortByColumns(
   Filter(
      SteelPulseR4,
      code = Code_Input.Text || 
      (
         Code_Input.Text = "<All>" && 
         Quarter = Quarter_Input.Text
      ) || 
      (  Quarter_Input.Text = "<All>" && 
         Game = Dropdown1.SelectedText.Value
      )
   ),
   "start",
   Ascending
)
