How can I create a dialogue/tick box which allows the user to select multiple choices and then put those choices in specific cells. (Drop down list only allows one choice)

Let say you click on cell A1, you get a dialogue box which allows you to tick 3 choices out of five.

Choices are France, Germany, Spain, Italy, UK, Norway. You can choose up to three of these countries you choice(s) should be shown in Cell A2, A3, A4
