need help with responsive filemanager

I should read library documentation carefully:

Select Image: (type=1 and set id of input text in field_id variable):
path to filemanager../filemanager/dialog.php?type=1&field_id=fieldID

this information what I needed. 
I solved my problem by:

1. By putting <input id="img-path" type="text" name="">  in my view
2. and opening filemanager using filemanager../filemanager/dialog.php?type=1&field_id=img-path this query

Can you please give me a example. I am very disturbed for intigrate this in your way plz help me send me a example or source code plzz
