How do we get the daterangepicker to accept no date. I just want to be able to clear it out.
You can set
autoUpdateInput: false as explained here
Then recompile your assets folder with Gulp or Webpack.
Please note that the build tools are required only in the development environment just to compile the assets when the source folder files are modified. In the hosting/server deployment you will only need the compile assets, no need to install the build tools dependencies there.
