I am new to Infopath and sharepoint.

currently I was tasked to design one registration form, I need do the following:

I have one drop list which contain 10 topics, each topics can contain many keywords.

for example topic1 has keyword11 keyword12, keyword13 ... etc.

topic2 has keyword21 keyword22, keyword23 ... etc.

when user clicked the topic1 , its keywords keyword11 keyword12, keyword13 ... etc. will dynamically show as Multiple Selection List Box.

when user clicked the topic2, its keywords keyword21 keyword22, keyword23 ... etc. will appends to list of the Multiple Selection List Box.

Here the number of Topics and number of keywords under each Topic is dynamic.

how can I achieve this purpose? can anymore give me some ideas?
