The company requires the page to add a code break processing
For example, color points: odd|even numbers
Size points: 1|2|3|4|5
Yes When an odd number is clicked, 1.3.5 is displayed as optional (2.4 is not optional, or it can be hidden).
The opposite result is displayed when an even number is clicked.
When the page is loaded, all attributes are displayed.
Please give me some advice, or if there is no similar case for me to learn from!

Give me a judgement When you click on *** , click odd or even, what will appear? What to do when you don’t order?
