Hi @morloderex,

Thanks for the PR, however please add tests and doc block as in contribution guide

[morloderex]

Sorry for the late reply.
i am not confident in creating tests in vue just yet. Can you help me out?

[mo3rfan]

Need something like this for the currency prop too! (I can open a PR for this)

@morloderex tests and docblocks added: morloderex#2 :)

[kevinongko]

Strange, I didn't find the changes from @powerinside in this PR, maybe @morloderex need to resubmit the PR?

[mo3rfan]

The changes went into his master branch instead of the feature branch. Sorry about that. Let's try again. PR: morloderex#3

[morloderex]

The pr should now be rebased against the correct branch. Thank you so much for helping me @powerinside !
