You can't conditionally change the options inside a Dropdown Menu. The only alternative you can do is to setup multiple Dropdown fields that will match your Condition.

e.g. Create 1 Dropdown with 1 to 5 and another Dropdown with 6 to 10, then conditionally show one of them depending on the input on the Textbox.

IF Textbox IS EQUAL to A THEN SHOW Dropdown with 1 to 5 fields

IF Textbox IS EQUAL to B THEN SHOW Dropdown with 6 to 10 fields

Since you're working with Dropdown Fields, it may be worth checking this widget too. I don't know what your workflow is but this allows dynamic options inside the dropdown widget: https://widgets.jotform.com/widget/dynamic_dropdowns
