How to add dynamic placeholder to a SXA Rendering Variant?

Question

Is there any way for me to add placeholders programatically inside the SXA rendering variant. I have tried using the * at the end of the name of placeholders but I keep getting some weird errors and the whole site just crashes.

Here is what I mean by this:

const string key = "carousel-1-*"
@Html.Sitecore().Placeholder(key)

I keep getting erros when I use this. Also, the model is VariantListsRenderingModel

Instead of placeholder, just need to DynamicPlaceholder like below -

@Html.Sitecore().DynamicPlaceholder("key")

No need to give *, this DynamicPlaceholder will manage a unique by itself like below -
