Have only one column A for fruit and another column B for Fruit type.
So, the first fifteen entries in column A are the name of the first fruit, and in the second column next to it, are the names of the Fruit types for the first fruit.
Have another column C containing only the names of all the fruits.
So, now you can have a choice component “Select Fruit” for Fruits in which you keep the source as values from column C and let it store the selection in a column “Fruit Selection”
For the next choice component “Select Fruit Type”, keep the source as values from Column B and have a filter, Fruit (Column A) equals to the column to which the first choice component stores the value which is “Fruit Selection”. So, it will show only the types for the selected fruit in the previous choice component.
