How to access drop down in webview. (Robot framework+Appium+Hybrid App)

Hi Guys,

I am working on robot framework + Appium + Hybrid app automation combination.
I am stuck at a point where in I need to select values in drop down in webview.
There are no keywords to access drop down of webview in appium, If I add selenium library I am getting conflicts with already written keywords in script. Can someone help me it.
