The organization I work at (NASUVINSA/LURSAREA) is developing the cAAE project (Industry Catalogue of Navarre, Spain) in collaboration with the regional government. As part of the products of the project we are publishing a web app developed with Web AppBuilder. The public app allows to search for availability of industrial land as well as the current economic activities in the region. In order to improve user experience, we created together with ESRI Spain a custom widget (Advanced Identify) that allows to organize layer content in a more intuitive way. Feel free to test and use in your own projects. Although the user manual is in Spanish, I will upload an English version as soon as possible. In the meantime, do not hesitate to ask me any question. Hope you will find it useful.
You can see a live version HERE. (from November 4th 2016 on)
Looking forward to getting some feedback!
