Dialog --menu open another --menu bash - bash

Question

I just started to learn bash and create a GUI with Dialog, but I'm having a problem with my program, any help will be appreciate it. Thanks
I want to create a program which will display a dialog which will ls only directories from the current folder:
display_folders()
{
while true; do
let count=0 #define counting variable
w=() #define working array
while read -r line; do #process file by file
let count=$count+1
w+=("$line" "$line")
done < <(ls -d */)
file=$(dialog --title "List directory" --cancel-label "Exit" --no-tags --menu "Please choose one folder: " 10 40 0 "${w[#]}" 3>&2>
#clear
exit_status=$?
echo $exit_status
case $exit_status in
1) echo "Program terminated"
exit ;;
255) echo "Program aborted"
exit 1 ;;
esac
echo "this is $file"
case "$file" in
*)
cd $file
display_result "$file" ;;
esac
done
}
After selecting the specified dir (for example ANIMALS) I want to cd into it and make some actions (the code is just for the 1 selection)
display_result()
{
while true; do
selection=$(dialog --title "folder" \
--cancel-label "Exit" \
--menu "Choose an action: " 10 40 0 \
"1" "List details about files" \
"2" "Search for word" \
"3" "Generate CSV" \
"4" "More info CSV" \
"5" "Search file" \
3>&2 2>&1 1>&3)
exit_status=$?
case $exit_status in
1) break ;;
255) echo "Program aborted"
exit 1 ;;
esac
case $selection in
1 )
result=$(ls -lt)
display_file_details ;;
esac
done
}
display_file_details()
{
dialog --title "file details" --no-collapse --msgbox "$result" 0 0
}
The problem is, in the selected folder (ANIMALS) I have another folder too (for example OTHERS), when I am ls all from the folder ANIMALS it will display me everything (which is good), but after I exit from the display --msgbox will display me another --menu only with OTHERS folder, and the display_result for it, if I exit from this too, the program will exit with 1 code.
What I want is to cd into ANIMALS, which is the dir from current folder, then list the options (1,2,3,4,5), and after exit from the options display I want to take me back to my current folder with ANIMALS in it.

You don't need this 'while true; do' loops. Create first dialog:
dialog1(){
list=( */ )
folder=$( dialog --title "List directory" --cancel-label "Exit" \
--no-items --menu "Please choose one folder: " \
--output-fd 1 10 40 0 ${list[#]///} )
echo $folder
dialog2
}
And the second like this:
dialog2(){
# another dialog here
# some code here
dialog1 # run first dialog again
}
And start first dialog:
dialog1
p.s. check out my projects sshto and kube-dialog created via dialog.

Thank's #Ivan but this is not what I wanted.
I solved it by going back with a dir in the same case :
display_file_details()
{
dialog --title "file details" --no-collapse --msgbox "$1" 0 0
}
dialog1(){
list=( */ )
folder=$( dialog --title "List directory" --cancel-label "Exit" \
--no-items --menu "Please choose one folder: " \
--output-fd 1 10 40 0 ${list[#]///} )
exit_status=$?
echo "$exit_status dialog1"
case $exit_status in
1 | 255)
return 0
;;
*)
diag2_return=255
while [ "$diag2_return" -ne "0" ]; do
dialog2 $folder
diag2_return=$?
done
esac
return 1
}
dialog2(){
echo "hereeeeeeeeee $1"
selection=$(dialog --title "folder" --cancel-label "Exit" \
--menu "Choose an action: " --output-fd 1 10 40 0 \
"1" "List details about files" \
"2" "Search for word" \
"3" "Generate CSV" \
"4" "More info CSV" \
"5" "Search file" )
exit_status=$?
echo "$exit_status dialog2"
case $exit_status in
1 | 255)
return 0
;;
esac
case $selection in
1 )
cd "$1"
result=$(ls -lt)
display_file_details "$result"
cd ..
;;
esac
return 1
}
diag_return=255
while [ "$diag_return" -ne "0" ]; do
dialog1
diag_return=$?
done
