hi at last u made , bubbles true and composed false then event didnt propagate beyond parent comp, but without bubbles true also same thing will happen so whats the diff?plz clarify

[@santosh6693]

in grandparent Html cant we directly get event value from child instead of calling like to something like . i didnt get why to use parent component in grandparent ..bcz we are already making bubble as true it will propagate to upward till root.

[@nishantkumar-vv8pf]

I didn't get the part of bubble true and shadow false.
So here what u meant to say is if we have child and parent component ... Child embedded in the parent then two different shadow where one is default DOM and other is the child component shadow dom embedded in default DOM. So this creation of shadow DOM happens by default as we create a child component of parent.
Please answer

[@nishantkumar-vv8pf]

So if we have case which you shown child parent grand parent ... Then to pass the data from child to parent... Always we have to keep bubble as true and composed as true
Am j correct

[@tightsecured1175]

Hi
I had a doubt I men if we need both composed:true as well as bubbles: true to propagate to grandparent what use does only bubbles:true and composed:false have.
I did not understand this part.

[@aamirkhan144]

So Bubble is true ,meaning you allow events to flow towards till the parent root level. And Composed true meaning you allow the event to read all the parent shadow elements.
I hope it answers your question.
