How can I choose the Inputs in the input dialogue box and enter value of the selected ones ?

I want a dialogue box which asks users to choose the Inputs(Variables of a function) they want to give and then enter their values as input.

As an example,

Please choose atleast 2 Variables from below

u

R

H

t

theta

th

ux

uy

If I choose u and theta then in the next dialogue box (or in the same dialogue box) I can enter the value of variables I've chosen. I also want to display some text over that box for instructions like units of variables etc.

list={'ux','uy','t','u','theta','x','y','r','R','H','th'}
[indx,tf] = listdlg('ListString',list,"SelectionMode",'multiple')

%list1 is column vector that contains text I want to display in the upcoming dialogue box
list1=["Enter a value of ux in m/s";"Enter a value of uy in m/s";"Enter a value of t in s";"Enter a value of u in m/s";"Enter a value of \theta (in degrees)";"Enter a value of x in m";"Enter a value of y in m";"Enter a value of r in m";"Enter a value of R in m";"Enter a value of H in m";"Enter a value of th in s"];

% PROMPT IS NOT WORKING PROPERLY !!!
prompt = {'',strjoin(arrayfun(@(x) num2str(x),list1(indx),'UniformOutput',false),''',''')};

dlgtitle = 'Input Value';

% HOW TO CHANGE DEFINPUT VALUES ACCORDING TO THE CHOSEN INPUT VARIABLES?
definput = {'0','0','0','0','0','0','0','0','0','0','0'};

opts.Interpreter = 'tex';
answer = inputdlg(prompt,dlgtitle,[1 40],definput,opts);

I hope my problem is clear and understandable. Please feel free to ask any questions.

How can I resolve this issue ?

I have made some changes in your code and I think it is working fine now. I have just added items to prompt and definput dynamically based on the indx vector which captures the indices of the inputs you have picked.

list={'ux','uy','t','u','theta','x','y','r','R','H','th'} 
list0=['Enter a value of ux in m/s',"Enter a value of uy in m/s","Enter a value of t in s","Enter a value of u in m/s","Enter a value of \theta (in degrees)","Enter a value of x in m","Enter a value of y in m","Enter a value of r in m","Enter a value of R in m","Enter a value of H in m","Enter a value of th in s"] 
list1=['1','2','3','4','5','6','7','8','9','0','1'] 
[indx,tf] = listdlg('ListString',list,"SelectionMode",'multiple') 
prompt=[] 
dlgtitle = 'Input Value'; 
definput = {} 
for i=1:length(indx) 
   prompt=[prompt,list0(indx(i))]; 
   definput=[definput,list1(indx(i))] 
end 
opts.Interpreter = 'tex'; 
answer = inputdlg(prompt,dlgtitle,[1 40],definput,opts);
