Hey all!

I’m trying to filter data by a column, I have an array of selected values that I want find in the data.

The column is named `symbol` and using `Inputs.select(list, {mutiple: true})` I can get an array of symbols, let’s say for example that `list` contained `["AAAA", "BBBB", "CCCC"]` and the user selected `AAAA` and `BBBB`.

How to return data rows that match that array for the colmun `symbol`?

I have tried to look in Arquero’s documentation but nothing came up for partial selection, maybe I missed something. Closest thing I got was

`df.filter(d => d.includes(d["symbol"], ["AAAA"]))` but this doesn’t work for  
`df.filter(d => d.includes(d["symbol"], ["BBBB", "AAAA"]))`

Thank you

Hi,

You’re close! You want to check if the selected values from the list include d.symbol. Something like this: df.filter(d =\> selection.includes(d.symbol))
