Remove some columns but make it available via "Add column..."

[rsakai]

Is it possible to remove some columns, but have them available under the "Add column..." dropdown?

Another way to ask this is, is it possible to trigger the "remove" on the LineUp object?

I have too many columns and I want to start with a basic set and give the user the option to add the columns they want. Maybe there is a way to do this from the builder, but I can see only those columns that I added via column() function under the "Add column..." dropdown. Any work around? or did I miss something obvious?

when you create lineup using the builder you can define how the ranking is being built.

e.g. in

lineupjs/demo/builder2.html

Lines 36 to 41 in 6a6a724

	const ranking = LineUpJS.buildRanking()
	.supportTypes()
	.allColumns() // add all columns
	.groupBy('cat')
	.sortBy('a', 'desc')
	.impose('number', 'a', 'cat2'); // create composite column

it creates a custom ranking with a specific sorting and a defined set of columns. I assume in your case only the "defaultRanking" is created which adds all available columns by default.

Thanks @sgratzl. I did something like the below and it is working. I hope this is what you meant...

 // create a builder
    const builder = LineUpJS.builder(my_data);
    // derive all columns
    builder.deriveColumns().deriveColors();
    // create a ranking
    const ranking = LineUpJS.buildRanking()
      .supportTypes()
      .column("col_01")
      .column("col_02")
      .column("col_03");
   // set ranking
    builder.ranking(ranking);
    const lineup = builder.build(document.getElementById("my-chart"));
