<h2>Editing the dataset</h2> |
|
|
|
<div style="width: 700px; font-size:14px; text-align: justify;"> |
|
|
|
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. |
