Q&A

• What happen if I have conflicted constrains? split-panel respects all constrains equally. The user need to make sure that the constrains does not conflict. For example: Here the leftMinWidth is bigger than the leftMaxWidth

<SplitPanel leftMaxWidth={200} leftMinWidth={300}>
  <div>a</div>
  <div>b</div>
</SplitPanel>
