it works only very first time and then it loses position

[dhboys]

Hello, I'm frontEnd developer in South Korea.
I've found lib to make layout like 'Pinterest' and I've got this lib.
I mean, thanks to make this lib.

anyway, I've got little problem using this lib.
it works very first time but when some states change it lost it's position.

for example,

1. when i come in the website
   

2. change the states (category is changed)
   

when it work right, Masonry tag has the style={{ position: relative; }}, but when it not works, it lost style={{ position: relative; }}
it could be the cause ?
thank you for reading, I look forward to reply, thank you.

I solve the problem.
just put the stlye={{ position: 'relative'; }} to Masonry's parent tag.
