Conditional Drop Down Field

Is there a way that we can only show some of the options from the multiple choice field based on another field?

For example, if the grade field is listed as Pre-K, K or 1, then only the first two options of the multiple choice (Select the camp .....) will show up.

Is that possible with conditional formatting?  If so, can you help me set it up or let me know of a workaround?

Here is the link of the form I am working on.

Thank you,

Unfortunately, we are not able to change multiple choice field options via conditions. You need to create separate multiple choice fields for each option in the dropdown. After you can show the related multiple choice field according to the selected dropdown option.

Is there a way to do two conditionals?

For example, if the grade is prek,k,1, OR 2 AND they select week 1 then show optio A of dropdown fields?

Yes, you can create this kind of composite conditions. You need to use update/calculate conditions. Please look at these steps.
1. We are not able to check multiple choice fields with conditions directly. Please collect the selected options into a form calculation widget to know which options are selected. Do not forget to hide it.
2. Please insert the multiple choice field into the form calculation widget. Please make sure the field is a string(brown - Step 2). 3. I assumed the dropdown is "T-Shirt" field. Please create this condition to show the "Youth Large" option in "T-Shirt" dropdown if "Grade" is "1" and "Week 1" selected. 

This is my demo form.

And this is a sample. And I also noticed that your form has some conditions with errors. Please remove or disable them. They may make your form unstable.
