<h2>Editing the dataset</h2>
|
|
<div style="width: 700px; font-size:14px;">
|
|
In this example we have enabled the data manipulation setting. If the dataManipulation option is set to true, the edit button will appear.
|
|
If you prefer to have the toolbar visible initially, you can set the initiallyVisible option to true. The exact method is described in the docs.
|
|
<br /><br />
|
|
The data manipulation allows the user to add nodes, connect them, edit them and delete any selected items. In this example we have created trigger functions
|
|
for the add and edit operations. By settings these trigger functions the user can direct the way the data is manipulated. In this example we have created a simple
|
|
pop-up that allows us to edit some of the properties.
