I have a multi-site project in yii2 that has several themes. Through “Theme Inheritance (http://www.yiiframework.com/doc-2.0/guide-output-theming.html)” I have managed to do that if there is no view in a theme that is tried to load then it loads it from the predefined theme. So I do not have to modify all the same views every time I make a modification. My question is … can this be done with the assets? I mean, if I do not have an asset in the theme folder I want to load it from the predefined theme folder. I do not know how I could do it. Let’s see if you can help me. Sorry for my bad English!
