Problem

Researchers often need to create new categorical variables based on conditions from existing variables (e.g., grouping a numeric variable into bands).

Currently, this requires writing conditional JavaScript, such as:

if (sumCola < 5) 1;

else if (sumCola >= 5 && sumCola <= 10) 2;

else if (sumCola > 10) 3;

else NaN;

This creates a barrier for non-technical users and increases the likelihood of syntax errors.

Proposed Feature

Introduce a point-and-click interface for creating new categorical variables using logical conditions.

What It Should Do:

* Allow users to select an existing variable

* Define conditions using dropdowns (e.g., <, <=, >, between)

* Add multiple condition rows visually

* Automatically assign category values and labels

* Generate the underlying logic without requiring JavaScript

Impact:

* Removes reliance on code

* Reduces errors

*Makes variable creation faster and more accessible for all researchers
